XWD型臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥式靜(jing)電(dian)除塵(chen)器是以(yi)靜(jing)電(dian)凈化(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)粉(fen)塵(chen)，它(ta)的(de)(de)(de)凈化(hua)工作上(shang)要(yao)是依靠電(dian)暈極(ji)(ji)(ji)和(he)沉(chen)淀兩個(ge)系統來(lai)完成(cheng)的(de)(de)(de)，當(dang)含塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體(ti)受到氣(qi)(qi)(qi)流(liu)分(fen)(fen)布板以(yi)及(ji)折流(liu)板的(de)(de)(de)調整(zheng)后(hou)(hou)，使(shi)(shi)氣(qi)(qi)(qi)流(liu)能較均勻地(di)進(jin)人(ren)電(dian)場(chang)。在(zai)橫斷面(mian)擴大(da)(da)的(de)(de)(de)作用(yong)下(xia)(xia)，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低(di)，其中(zhong)有些較重的(de)(de)(de)塵(chen)粒便失去速(su)度而沉(chen)降下(xia)(xia)來(lai)。進(jin)人(ren)電(dian)場(chang)的(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于(yu)電(dian)暈極(ji)(ji)(ji)通人(ren)高壓(ya)直流(liu)電(dian)，則(ze)在(zai)電(dian)暈極(ji)(ji)(ji)附近(jin)產生電(dian)暈現象(xiang)，使(shi)(shi)氣(qi)(qi)(qi)體(ti)電(dian)離(li)(li)(li)，電(dian)離(li)(li)(li)后(hou)(hou)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在(zai)大(da)(da)量(liang)的(de)(de)(de)電(dian)子和(he)離(li)(li)(li)子，這些電(dian)子和(he)離(li)(li)(li)子與進(jin)人(ren)電(dian)場(chang)的(de)(de)(de)粉(fen)塵(chen)結(jie)合起來(lai)，使(shi)(shi)塵(chen)粒帶電(dian)，帶電(dian)塵(chen)粒在(zai)電(dian)場(chang)力(li)的(de)(de)(de)作用(yong)下(xia)(xia)趨(qu)向本(ben)(ben)設(she)備(bei)陽極(ji)(ji)(ji)(正極(ji)(ji)(ji)、本(ben)(ben)設(she)備(bei)采用(yong)負(fu)高壓(ya)制)和(he)陰極(ji)(ji)(ji)(負(fu)極(ji)(ji)(ji)) ， 釋放(fang)出電(dian)子分(fen)(fen)別(bie)沉(chen)積在(zai)相應的(de)(de)(de)電(dian)極(ji)(ji)(ji)上(shang)，通過設(she)備(bei)陰陽極(ji)(ji)(ji)振打系統的(de)(de)(de)振打，使(shi)(shi)沉(chen)積在(zai)陰陽電(dian)極(ji)(ji)(ji)上(shang)的(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)集(ji)灰斗 通過排灰裝(zhuang)置放(fang)出，回(hui)收有物料，被(bei))凈化(hua)的(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入(ru)大(da)(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)工(gong)作原(yuan)理是利用高壓電(dian)(dian)(dian)(dian)(dian)(dian)場使(shi)煙氣(qi)(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)(dian)離，氣(qi)(qi)流(liu)中(zhong)的(de)粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)場作用下與氣(qi)(qi)流(liu)分離。負極(ji)(ji)(ji)由(you)不同斷面形(xing)狀(zhuang)(zhuang)的(de)金屬導線制成(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。正極(ji)(ji)(ji)由(you)不同幾何形(xing)狀(zhuang)(zhuang)的(de)金屬板制成(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)器的(de)性能受粉(fen)塵(chen)(chen)(chen)性質、設備構造(zao)和煙氣(qi)(qi)流(liu)速等三個(ge)因素的(de)影(ying)響(xiang)。粉(fen)塵(chen)(chen)(chen)的(de)比電(dian)(dian)(dian)(dian)(dian)(dian)阻是評(ping)價導電(dian)(dian)(dian)(dian)(dian)(dian)性的(de)指標，它對除塵(chen)(chen)(chen)效(xiao)率有直接的(de)影(ying)響(xiang)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過低，塵(chen)(chen)(chen)粒難以(yi)保持在集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)上(shang)，致使(shi)其重返氣(qi)(qi)流(liu)。比電(dian)(dian)(dian)(dian)(dian)(dian)阻過高，到達集(ji)塵(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)的(de)塵(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)(dian)荷不易放(fang)出，在塵(chen)(chen)(chen)層之間形(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)壓梯度會產生局(ju)部擊穿和放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)現象。這些情況(kuang)都會造(zao)成(cheng)除塵(chen)(chen)(chen)效(xiao)率下降。

電(dian)除塵(chen)(chen)(chen)(chen)器的(de)(de)基本(ben)原理是(shi)利用電(dian)力捕集煙(yan)氣中的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)，主(zhu)要包括以下(xia)四(si)個相(xiang)互有關(guan)的(de)(de)物理過程: (1) 氣體的(de)(de)電(dian)離。(2) 粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)荷(he)(he)電(dian)。(3) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)(chen)(chen)(chen)向電(dian)極(ji)移動。(4) 荷(he)(he)電(dian)粉(fen)(fen)塵(chen)(chen)(chen)(chen)的(de)(de)捕集。
